IT 同 姨姨(EE) 結合既項目

時事板有帖,好值得 IT 板討論。

星島日報報導

安徽合肥工業大學翡翠湖校區的第三飯堂,近日推出智能結算系統,只要把餐盤放在結算區,就能自動計算出飯菜的價格。由於效率高又準確,備受該校師生歡迎。
智能結算系統並有兩台,並分為等候區和結算區兩個區域,結算區還有一塊電腦顯示屏。當學生將托盤放置在結算區時,顯示屏便可顯示出菜名和價格。學生只需要把飯卡放置在讀卡區,結算器會自動扣去相應金額。
而自從有了智能結算系統,到第三食堂吃飯的教師和學生明顯增加。有同學表示,以前用刷卡機,要花時間算價錢,有時候還會算錯。現在有了智能結算系統,不單省時還不會有失誤。
至於操作原理,第三食堂經理梅銳表示,除了自動結算系統,餐盤都是定制的,而且下面嵌有芯片。
據了解,餐盤放置在叫菜區顯示屏上時,餐盤裡的芯片就自動記錄了飯菜的價格信息。結算區通過感應這些餐盤中的芯片,得出相應數值。在安徽高校中,合工大是首個運用該系統的,而上海和杭州的高校早就啟用了。
據了解,系統稍後還會顯示菜品的熱量和脂肪等營養成分。除了能計算哪些菜更受歡迎,還能追踪學生的健康飲食,統計學生攝入多少熱量等。

個餐盤點洗?
唔係好明個新system點運作,用餐盤粒chip keep住running total?攞一樣餸隊個餐盤埋去拍卡?
定係有個鏡頭影到盤上有一碗飯一碟菜咁犀利?
取代的舊系統又有乜問題?

Just a general and simplifed description:
1. Each dish has a disposable chip containing an ID [Suppose you bought item A, B and C, then you will have a total of 3 chips]
2. When you go to the check out counter, there is a chip reader that reads the ID of the chips simultaneously [You may use the reader similar to Marathon, reader details and the scanning process vary according to the actual situation]
3. Once you obtained the IDs, you may get their corresponding details [e.g. dish descriptions, prices, vender name, nutrition information, etc] from a database
4. Once you calculated the total, you display the transaction details on screen and make a debit transaction to the PAYMENT card [The PAYMENT card contains a CardHolderID for identifying the cardholder]
5. You may store the transaction and other the useful information to a database based on the CardHolderID for future use.
Note:
A. You may enhance the system by having different discounts for teachers/students/visitors. You may distinguish a person's category by the PAYMENT card type he/she uses.
B. You may add a sensor so that the reader is activated only when there is "something" for the reader to scan to save energy.
Just my initial thoughts.

丁丁板友,我幾欣賞你不停追擊島主,而家仲學開曲綫球。

其實無人可以追擊你,除非你出D低能量,低維他命B帖,可惜,甘就 another story 啦.

你既論點,就好似話: 而家人人買米都去超市,乜米都有,所以有超市就無糧食問題。開超市係重點。不過,你唔會明我類比係講乜。

一粒 Intel Xeon E5-2965 CPU, 可以零售港幣一萬九千多。老老實實,多過你一個月糧。

Software 增值,所以也可以賣到錢,但去講軟件會替代硬件,硬件會息微,係低B班。唔明? 地產項目發展商(software) 好賺過建築工程公司(hardware),但你會唔會話無乜結合? 甘講就真係白紙一張。

你要講既,係份工,做建築工人,定地產發展,而唔係成個行業。

深思下啦,或者黎吓高班做旁聽生,呢個板唔太識合你回帖啦,免得你D帖文又追擊番你自己!

I stick to the core part - purchase data capture. (I didn't research all the details but just guestimate how it works.)

It is quite a clever design to use 2-pass to achieve the data capture - 1st pass to write the purchase data, 2nd pass to read them back at checkout.

Here is my guess:

1st pass - when the tray is being docked at the particular food area, the area's chip writer will update the chip embedded in the tray. For example, when the tray is docked at two-choice meal, a writer will write to the tray's chip of such - "one" order of two-choice meal. Likewise for drinks that are same price, there is a writer (at the docking area). By separating the writer for each type of food SKU (stock keeping unit), it avoids using RFID tag in every food package. It is a lot of saving on the RFID tags.

2nd pass - now the tray has been written with all the food/price info, the check out counter's reader will pickup all info.

Insofar, my questions - what if I picked up the food but didn't allow the tray to dock, so that the food SKU cannot be written. Then an associated question - how do they handle multiple qty? Thru honest system the purchaser to dock one more time?

早晨呀,倉鼠兄!

RFID 成本低,但食品有難度。

我估,佢巧妙用左托盘先系個 RW chip, 唔同位置放唔同食物擺放有 writer, 有40類單品 sku, 有40個或以上writer,  你攞要嘟一下,甘果個 writer 就寫入個托盘粒chip到,食物飲品唔洗 rfid tag. 到 checkout, 個 tray 粒 tag 已經有晒D purchases, check out 仲易,唔洗去讀 multiple rfid tag.

要真的留意下商業應用層面,不只係 tag 呀, 讀呀,仲要諗下点真實應用落去。

厨房出23個兩餸飯盒,廿蚊合,27個意粉,廿二蚊盒。你要好似机埸打印行李带甘,出食品時打印,燒價錢落去每張 rfid. 唔打印,又或者 preallocate 你個 unique serial number,甘又係大鑊。即系 id 1xxxx 係一律兩餸飯,id 6xxxx 系意粉,id 15xxxx 係熱朱... 三個月賣左一萬個餐,running out of preallocated range, 点算。Prealloc 10個位 running, 4個位 prefix 係代表食物單品? 仲有無複雜D。See the problem?
